How does asthma drug alteration someones breathing or heart rate?(albuterol sulfate)?
Answer:
heart rate increases. albuterol sulfate is related to adrenaline.
In general, asthma medication attempts to mimic a sympathetic response >>> bronchodilation by stimulating SPECIFIC receptors, more than ever beta 2 adrenergic receptors, because beta 1 receptors would cause an increase within heart rate, which you do not necesarrily want.
Bronchodilation of course open up the airways, improving O2/CO2 exchange.
Albuterol is a short acting beta 2 adrenergic agonist. It act by stimulating the adrenalin (epinephrine) receptors in the bronchial tubes of your lungs which motive the smooth muscle to relax and open up your airways.
The adrenalin receptors within you lungs are primarily beta2 and the receptors in your heart are primarily beta1. Unfortunately, in that is still some activity of albuterol on your heart's receptors. When these are stimulated, they can mete out a rapid heart rate.
Albuterol can also affect adrenergic receptors elsewhere within your body, including the skeletal muscles and nerves resulting in shaking or tremors.
